Closely held Tealeaf, located in San Francisco, provides real-time insights about Internet spending on mobile and desktop devices, IBM said Wednesday in a statement. IBM, based in Armonk, New York, didn’t disclose terms of the acquisition.

The world’s largest computer-services provider expects software to deliver half of its earnings in 2015, driven in part by its Smarter Commerce initiative. IBM has made more than $3 billion in acquisitions, including Unica Corp. and DemandTec Inc., to add software tools that help businesses uncover trends, improve online transactions and better deploy their employees.

Tealeaf was founded in 1999 and spun off from SAP AG, the biggest maker of business management software. It has more than 450 customers worldwide in financial services, travel, retail and communications services, including Dell Inc., Wells Fargo & Co., Zappos.com Inc. and Best Buy Co.
